Separation of coal conversion wastewater components by reverse osmosis

Conference ·
OSTI ID:5723777
Studies of reverse-osmosis separation of process-derived components from aqueous streams conclude that aromatic-polyamide membranes generally provide better rejection of coal-conversion wastewater components than cellulose-acetate membranes, especially with regard to nonionized organic components. The pH of the feed stream strongly influences the rejection of ammonia, bicarbonate, sulfide, phenol, and borates. Separation of bases (ammonia) decreases with pH, while the separation of acids (bicarbonate, sulfide, phenol, and boric acid) increases with pH.
